Yann E. MORIN" e960f66953 cc/gcc: install the core compilers in the build-tools dir 
There really is no good reason to install the core compilers in their
own places, one for each pass. We can install them with the other
build tools.

Also, this implies that:
 - there are fewer directories to save/restore
 - there are fewer symlinks to create for binutils
 - the PATH is shorter
